Halog scaler screens, both arm roughly at the same time.
2. Change both arm momentum to P_HRS=1.1759
3. Carbon multi-foil runs, raster off, both arm. Take T1 and T3. For detector check, shower calibration, etc. take a few runs, Email Vince these run number.
4. Hydrogen reference cell runs. Reference cell H2, (~100 psi good enough). H(e,e'p) cross calibration. P_HRS=1.2112 (delta=+3%), Make sure BigBite MWDC are on. BigBite trigger working, Run, left arm DAQ read in BigBite, left arm T5 prescale=16777215. Run, right arm DAQ read in neutron arm.
Raster On, standard setting on the board.
Take a few runs, 10 min each, expert check BigBite and neutron arm detectors. When verified that detectors are reasonable, stop.
5. P_HRS=1.1759 (delta=0%), take a few runs.
Take a few runs, 10 min each,
6. Set P_HRS=1.1406 (delta=-3%) on both arm, repeat step-4. Take a few runs, 10 min. each.
Take one carbon multi-foil run, T1/T3 1 million events, BB and neutron arm doesn't matter. Email Vince these run numbers again.
7. Call for controlled access, Brad to install sieve slit plate.
At the same time, set both P_HRS=1.275 for the next delta=+3.0% scan point.
During the day Saturday,
8. For carbon sieve slit runs, optics, momentum settings:
i. Delta=+3.0% P_HRS=1.275 ii. Delta=0.0%, P_HRS=1.238 iii. Delta=-3.0% P_HRS=1.200
9. H(e,e') sieve slit runs,
i. Delta=+3.0% P_HRS=1.2112 ii. Delta=0.0%, P_HRS=1.1759 iii. Delta=-3.0% P_HRS=1.1406
